700 isn’t enough to build a 3070 pc unless it’s bottleneck city

I agree, you need to review that $700 spending, unless you want last generation or two generations ago of PC parts.

Generally, below is the cost rundown of your PC parts.

Motherboard - $200, you can find some cheaper for sure, like $170 or $180. Going last generation, it'll be a bit more cheaper.
PSU - $120, given the RTX 3070 recommending a 650W, and you should go for Gold rating, $120 seems like the starting point.
RAM - $100, if you find some on sale, go for them.
CPU cooler - $100, you can definitely find something cheaper if you don't go for Noctua brand.
Case - $100, you can definitely find something cheaper but it becomes a piece of metal at lower prices.
CPU - $250, if you're going for last generation AMD Ryzen 5 3000 series or Intel i5 9000 series (two generation ago) or 10000 series (last generation).

would pairing a 3600 with a micro atx for around 350-360 suffice?

That's possible. I think you can find a Ryzen 3600 and a motherboard for under $350.

Right now, NewEgg and Amazon has the Ryzen 3600 for $210 and $235 respectively. There's a chance NewEgg might put the 3600 on sale, or you can find with a cheaper motherboard, below $150.

The Ryzen 3000 series will work on the older chipsets (motherboards), such as X470 and B450. But with these chipsets, they support PCIe Gen2. Right now, current generation is PCIe Gen4. Your RTX 3070 runs on PCIe Gen4...

The parts look compatible and you'll be able to use them to their fullest potential. The only thing you're missing there is the CPU cooler...

Try going for the Western Digital Blue Gen3 (or NVMe 3 or PCIe 3) because NewEgg has them for $60.

i thought amd always came with a cooler?

Yes, you're correct. The Ryzen 3600 does come with a cooler. I forgot that fact.

Does a 3070 even fit in a micro atx case
